With the continuous improvement of the requirements for the operating environment and the quality of surgery, the construction of a high-standard clean operating room has become one of the key points in the development and construction of the hospital. The construction, layout, workflow and management of the operating room must be designed around sterile requirements. Expanding the new model of operating room management, fully applying electronic intelligent equipment in the daily work of the operating room, improving the efficiency and management efficiency of the operating room, and realizing the transformation from the traditional management model to modernization and scientification. It has become a hospital operating room application. The new direction of information management.
The traditional operating room management process is as follows: manual registration of personnel entering and exiting, manual distribution of clothes and shoe cabinet keys and surgical gowns, free meals in the operating room during the operation, replacement of surgical gowns in the dirty clothes basket after the operation, and return of the clothes and shoe cabinets before leaving the operating room key. The process has the following problems: manual registration is easy to make mistakes and omissions, and it is difficult to check the access rights and number control; the issuance and recovery of locker and shoe cabinet keys cannot be monitored and returned in real time, resulting in insufficient resources and affecting the opening of the operation; manual distribution of surgical gowns, workload The user cannot be traced back. The misappropriation or loss of surgical gowns causes insufficient turnover, forcing continuous repurchase, and waste of resources; it is difficult to track and supervise the dressing and walking routes of the operating room personnel, which may easily cause infection during the entry and exit process; it is difficult to record the time of going on and off work, which affects the operation The opening of the table is punctual; it is impossible to accurately count the qualifications and number of dining personnel, which increases the cost of the operating room.
These managements relying solely on people and systems can no longer achieve effective control goals. They not only reduce the cleanliness of the operating room, and there are hidden dangers of infection, but also increase the investment of manpower and material resources, and sometimes cause conflicts in interpersonal relationships.
Therefore, when the operating room of our hospital is undergoing functional zoning and decoration and expansion in 2015, through the research and development of a digital management intelligent surgical auxiliary area management system based on the combination of RFID technology and IC card, it solves the problem of identification of operating room personnel and surgical gowns.
